Would recommend viewing the YouTube videos that OSIsoft have posted to see some of the functionality of PI Webparts and PI Coresight (which is really quick and easy to use on both the PI AF and PI Data Archive points directly). Search YouTube for OSIsoft + Coresight.
Have you gone further with you project?
AF is definitely something that can bring a structure to the PI System Data.
As Stephen proposed, this is a good thing to look at PI Coresight, it is a very nice way for users to go and explore the data.
And OSIsoft Youtube channel proposes a lot of content you can look at to know more about our products.
If you would prefer to go with a programmatic approach, we have PI Data Access technologies that provide you with many ways to access PI System data programmaticaly, see this KB for a comparison:
KB01046 - PI Data Access Features
Hope this helps
It's been a while since we spoke about this issue. Did you have a chance to look at PI Coresight and some of PI Data Access technologies referenced by Patrice?
I'll go ahead and mark this question as assumed answered. If you need further help do not hesitate to post again on this thread.
